g 13 Claims." (01.- 235-3) This invention relates to cash registers and the like, and particularly of the type shown in United States Letters Patents, Nos. 751,611 and 773,053, granted to Thomas Carroll on Febru- 5 my 9, 1904 and October 25, 1904, respectively.

Machines of the type shown in the above named patents are provided withlevers adapted to be diiferentially positioned to set up amounts and various other data, which levers differentially position totalizer actuators. After the totalizer actuators are thus positioned by the levers, the totalizer ismoved into engagement therewith, and then moved relatively thereto, so that the amount set up in the actuators is entered into the totalizer, after which the same is disengaged.

The printing mechanism inmachines of the type disclosed in the above mentioned patents is usually located at the left side thereof, the type being set under control of the actuating racks in the manner fully described in said patents. Such printing devices may be arranged to print and issue checks or to print upon insertable slips or cards as desired.

In the present embodiment the printer is controlled to take either two impressions during an operation of the machine, or none at all. The two impressions may bemade on one card or on two separate cards.

It is in connection with a machine having a printer adapted to print upon one or more inserted cards, that the present invention is associated. When printing on a plurality of cards during a single operation it is sometimes necessary to print upon different lines, remotely spaced from one another on those cards, that is, it may be desirable toprint upon line 2 of the first card and line 8 of the second card. Under these conditions it is quite difficult to provide a feeding device for the second card that will feed it the distance required after the first card has been printed upon, and therefore, it becomes necessary to shift the second card to the proper line by hand, and since the speed at which the machine operates prohibits the manual withdrawal of the first card and the proper insertion of the second card during the machine cycle, a novel means has been provided to interrupt the operation of the machine after the imprint has been made on the first card.

One type of interrupting device is shown in United States Letters Patent, No. 1,658,993, granted to L. G. A. Kommling on February 14, 1928.

In the machine shown in this latter patent,

there are two motor bars provided, one to re lease the machine at thebeginning of an operation, and one to release the machine after the machine has been stopped, sothat it may complete its operation.

It is an object of the present invention to pro- 5 vide a machine of the type shown in the two Carroll patents above mentioned with two totalizers interspersed one with the other in place of the single totalizer shown in the above mentioned patents.

It is also anobject to provide a mechanism under the control of an adjustable manipulative device to select one or the for operation.

other of the totalizers desired line thereon.

It is a further. object of the present invention to control a consecutive number actuating device driving mechanism so that-it will be rendered ineffective during certain operations depending upon which of the totalizers has been selected for operation.

With these and incidental objects in view, the invention includes certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims and a preferred form or embodiment of of this specification. In the drawings:

the pres- IN GENERAL Generally speaking, the shifting of the totalizers into and out of cooperative relation with the actuators is used to control and determine the kind of an operation through which the machine will go, that is, whether or not that operation will be interrupted before the machine completes one complete cycle. When a certain one of the totalizers is selected, in this specific case the right-hand one, the machine is interrupted after it completes about one-half of its cycle to allow the operator to adjust record material to receive a printing impression upon the line desired. When the lefthand totalizer is selected, the machine goes through a complete cycle without any interruption whatsoever.

The two totalizers shown in Fig. 5 are interspersed, the first, third and fifth wheels, beginning at the right, belonging to one totalizer; and the second, fourth and sixth wheels, beginning at the right, belonging to the other totalizer, the latter being one which is not adapted to be reset to zero, and the former being adapted tobe restored to zero at the will of the operator. In other words, the right-hand totalizer is a subtotalizer, and the left-hand totalizer is a grand totalizer.

The selection of the totalizer to be operated, in addition to determining whether or not the machine will be interrupted during its operation, also controls the actuation of a consecutive numbering device.

DETAILED DESCRIPTION Keyboardand differential mechanism The keyboard and differential mechanisms of the machine to which the present invention is shown applied are not illustrated, nor will they be described in the instant case, since they are substantially identical with the keyboard and differential mechanisms shown in the two Carroll patents previously mentioned, and reference is to be made to these patents for a general understanding of the type of machine with which applicants invention is associated.

Totalizer Each of the above mentioned patents discloses a single totalizer, but, as previously stated, in the present invention applicant uses two totalizers which he has interspersed one with the other, they being of the same general type as is shown in the Carroll patents. Fig. 6 shows a cross section of the Carroll type of machine with the necessary modifications of the totalizer illustrated, It is, therefore, not thought necessary to go into any detailed description of the totalizers, and they will be somewhat briefly referred to.

The interspersed totalizers include adding wheels 12 (Figs. 5 and 6) and 13 (Fig. 5) arranged in groups corresponding to the value of the respective denominational orders. These wheels are carried upon a shaft 11 journaled in a totalizer frame 14, which is guided to move in bars 15 pivoted in the machine frame, in the manner that bars 122 are pivoted in frame 34 of the Carroll Patent 751,611, illustrated in Figs 1 and 2 of said patent.

All adding wheels 12 and 13 are arranged in a laterally shiftable frame 16, which frame is shifted relatively to the pivoted frame 15.

Totalizer shifting mechanism The means for shifting the totalizers laterally for selecting purposes will now be described.

Connected to the laterally shiftable frame 16 (Figs. 5 and 6) is a rod 17 carrying a pin or roller 18 entered in a slot of a shiftable slide 19. This slide has cam slots 20 and 21 at its upper and lower ends, respectively, by means of which slots it is shiftably guided by pins 22 and 23 mounted in the machine frame (not shown).

Upon the movement of a special selecting lever or key 90 and rack 25, the frame 16 is moved laterally in such a way that the adding wheels 12 or the wheels 13 are brought into cooperative engagement with the differential mechanism of the machine. With the parts in the positions shown in Fig. 5, the adding wheels 12 are in cooperative relation with the differential mechanism, and the pins 22 and 23 occupy the upper ends of the slots 20 and 21.

When the adding wheels 13 are selected for operation, the slide 19 is moved upwardly in a manner to be hereinafter described, and the pins 22 and 23 occupy the lower ends of the slots 20 and 21. Due to the shapes of the slots 20 and 21, when the slide 19 is moved upwardly, it is also moved to the left, as viewed in Fig. 5, which movement through the rod 1''! shifts the totalizer frame 16 into such a position that the adding wheels 13 will be in position to be actuated.

The slide 19 is provided with a stud 24 (Fig. 5) entered into a fork of a vertically reciprocable rack 25 (Figs. 1 and 3) having teeth at its lower end meshing with teeth of a disk 26 rotatably mounted upon a shaft 27. The disk 26 may have secured thereto a manipulative lever 90 (Fig. 1). This lever 90 is used to select one of the two totalizers 12 or 13 for operation. Movement of the lever clockwise from the position shown in Fig. l, rotates the disk 26 clockwise and raises the rack 25, whereupon the pin 24 raises the slide 19 to shift the totalizer frame 16 toward the left as viewed in Fig. 5, previously described.

Movement of the lever 90 back to its normal position lowers the rack 25, whereupon the stud 14 lowers the slide 19 to the position shown in Fig. 5, thus moving the totalizer frame 16 back to the position shown in Fig. 5, in which position the totalizer wheels 12 are in position to be oper ated by the actuator.

Machine drive and interrupting means The main drive shaft of the machine is shown at 36, Fig. 1, and may be operated manually by driving handles, such as shown in both of the Carroll patents previously mentioned, or in any other suitable manner. This drive shaft has means associated therewith to arrest its movement at the completion of one 360 degree cycle, and also mechanism associated therewith to interrupt or arrest its movement prior to the completion of said 360 degree cycle, depending entirely upon the totalizer selection. Such mechanism will now be described.

The rack 25 has secured thereto a bracket 28 (Figs. 1, 3, 5 and 6) having a large notch cooperating with a pin carried by a bell crank 29 pivoted at (Figs. 5 and 6) to the machine frame. This bell crank 29 also carries a pin 30 cooperating with the annular groove of a collar 31 secured to a shiftable shaft 32.

Also secured to this shaft 32 is an arm 33, the upper end of which normally lies in the path of movement of a long pin 35 carried by a gear 34 secured to the drive shaft 36.

When the rack 25 is raised by movement of the lever in the manner previously described, the lower edge of the notch in the bracket 28, by its cooperation with the pin in the bell crank 29, rocks the bell crank'clockwise, whereupon the pin shifts the shaft 32 and arm 33 to the left as viewed in Fig. 5. After the arm 33 has been shifted as just described, its upper end also lies in the path of movement of a shorter pin 37 carried bythe gear 34. V

This gear 34 has secured thereto arresting plates 38 and 38, one being appropriate to each pin and 37. Cooperating with these disks is a pawl 39 carrying a pin 40 engaging a slot in the arm 33. The pawl 39 has connected thereto a spring 42 tending to rock it counter-clockwise, as viewed in Fig. 1, and the arm 33 has connected thereto a spring 43 tending to swing it counter-clockwise.

When the shaft'36 is turned counter-clockwise by means of an operating handle, such as shown in the Carroll patents above mentioned, or any other suitable means such as a motor, it is adapted to receive one full rotation for each operation of the machine.

When the rack 25 is occupying the position shown in Figs. 1 and 3,'wherein the adding wheels 12 are in position for registering amounts received, the arm. 33 (Fig. 5) is in the path of the long pin 35 only, it being held out of the path of the shorter pin 3'? by the bracket 28.

When the parts are in these positions the shaft 36 is permitted to complete one 360 degree cycle of movement. Near the end of this movement the long stud 35 strikes the upper end of the'arm 33 and rocks it clockwise against the tension of the spring 43. This clockwise movement of the arm 33 through the pin 40 carries the pawl 39 clockwise against the tension of its spring 42 into a position whereby the nose of the pawl 39 will be in the path of a shoulder of the arresting plate 38, whereupon, as the shaft 36 completes its movement said shoulder, by its contact with the end of the pawl 39, stops the shaft 36 in itsnormal home position. Substantially at the time the cycle of operation is completed the stud 35 passes off the end of the arm 33, whereupon the latter is returned to the position shown in Fig. 1 by its spring but the pawl 39 remains in its effective retaining position.

When an operation of the same kind is to be started again it is necessary, as-is well known in the art, to give the shaft 36 a'slight reverse or clockwise motion just sufficient to disengage the plate 38 from the pawl 39, whereupon the spring 42 moves the pawl counter-clockwise into an ineffective position.

When, however, the proprietor of the establishment is collecting items, such as savings, which amounts are not to be accumulated upon the department totalizer 12, it is desirable to print multiple records in duplicate. For this reason the totalizer 12 is shifted to an ineffective position and the totalizer 13 brought into an effective position in the manner previously described by the movement of the selecting lever 90.

It has also been described how the movement of the lever 90 clockwise, .as viewed in Fig. 1,

through the disk 26, rack 25, bracket 28, bell crank 29, and shaft 32, shifts the arm 33 to the left, as viewed in Fig. 5, to bring its upper end into the path of movement of the stud 37 as well as the stud 35. With the parts in these positions, that with the arm 33 in the path of movement of the studs 35 and 37, upon the c0unter-clock wise movement of the shaft 36 and gear 34 the stud 3'7 will contact the upper end of the arm 33 and move it clockwise when the shaft 36 has completed only about one-half its movement. The

clockwise movement of the arm 33 at this time, through the stud 40, rocks the pawl 39 clockwise, whereby its upper end is in the path of a shoulder on the arresting disk 38', and consequently, the movement of the shaft 36 is inter upted or arrested at this point in the operation.

During the first half of this movement of the shaft 36, the printing mechanism to be later described is operated to effect an impression upon one record material. After the interruption of the shaft 36 occurs, the operator may remove the first record material and position a second rec- 0rd material to receive an impression during the second half of the operation of the shaft 36. After the new record material has been properly placed in the machine, the shaft 36 is rotated slightly clockwise to allow the pawl 39 to become disengaged from the shoulder of the disk 38', after which the counter-clockwise movement of the shaft 36 may be completed. Near its completion the pin 35 functions in connection with the arm 33 to stop the machine at the end of the operation in the manner previously described.

Printing devices The printing hammer is adapted to be latched against operation during the uninterrupted operations so that no impressions are made during such operations. When the machine is set to make interrupted operations, the printinghammer is released to permit it to take two impressions from the type carriers during the interrupted operations.

A hammer 45 adapted to print from type wheels 85 (Fig. l) is rotatably mounted upon a shaft 44. The hammer carries a stud 48 which rests against a bell crank 46 rotatably mounted upon the shaft 44. One arm of the bell crank is held in contact with a cam 49 by a strong spring 4'7. This cam 49 is secured to a shaft 50 rotated by gearing (not shown) driven from the gear 34. The cam 49 hastwo risers and two abrupt shoulders,,whereby the hammer 45 may be cocked and released twice during each complete cycle of operation, the spring 47 effecting a rapid counterclockwise movement of thehammer as the end of the bell crank 46 passes the abrupt shoulders.

. The disk 26 is provided with a second set of teeth 51 meshing witha segment 52 secured to a shaft 53'. Also secured to the shaft 53 is an arm 54 carrying a stud 55 projecting into a cam slot 56 of an arm 53 secured to shaft 57. Also secured to the shaft 57 is a bell crank 59 carrying a spring actuated locking pawl 69 which cooperates with a hammer 45 to prevent the operation thereof during uninterrupted operations in a manner to be presently pointed out.

When the totalizer selecting lever 90 is moved clockwise (Fig. l), the teeth 51 rock the segment 52, shaft 53, and arm 54 counter-clockwise, whereupon the stud 55 rocks the arm 53 and shaft 57 counter-clockwise, thus removing the pawl 69 from its cooperative relation with the hammer 4-5.

During the cycle of operation, which is uninterrupted, the shaft 53, arm 54 and stud 55 occupy the positions shown in Fig. 1, which holds the arm 58 and; bell crank 59 in a position whereby the pawl 60'is retaining the hammer 45 in the position shown, so that the same cannot be rocked against the type wheels 85 during such an operation.

The bell crank 59 is connected by a link 61 with an arm 62 pivoted upon a shaft 63. This arm 62 has a slot into which projects a pin 64 of a link 65 pivoted to a rocker arm 66 loosely mounted upon the shaft 53. This arm 66 is adapted to carry a consecutive counter actuating pawl (not shown).

When the parts are in the positions shown in Fig. 1, the pin 64 is resting in a slot or recess 68 in a stationary framework 86 shown by dot-anddash lines in Figs. 1, 2 and 4. When the pin 64 is in this position the consecutive counter actuating driving rocker arm 66 is disabled, so that during the operation of the machine the consecutive number wheels will not be operated.

However, when the parts occupy the positions shown in Fig. 4, in which the arm 62 has been raised by movement of the bell crank 59, the pin 64 then lies in a notch 69 01' a pitman '70 adapted to be reciprocated by a cam disk '71 (Fig. 2) secured to the drive shaft 36. During the reciprocatory movement of the pitman '70 the rocker arm 66 is rocked about the shaft 63 through the medium of the stud 64 and link 65 to efiect an operation of a consecutive numbering device of the usual character (not shown).

Simultaneously with the locking of the printing hammer 45 by the pawl 60 in the manner previously described, the arm 62 is retained in the position shown in Fig. 1 by the link 61, wherein the stud 64 is retained in the recess 68 in the stationary frame 86, thus preventing any movement of the consecutive number actuating device driving arm 66.

The number of times which the machine is interrupted in the cycle depends wholly on the number of arresting plates 38' that are used.
